Abstract:
Techniques for supporting data transmission with little or no control overhead are described. In an aspect, data may be sent based on a hybrid scheme that utilizes a combination of group hopping for transmissions of new packets and static grouping for retransmissions of pending packets. For the hybrid scheme, a user equipment (UE) may be assigned different resource blocks in different transmission intervals based on a hopping pattern. The first transmission of new packets may be sent on resource blocks determined based on the hopping pattern. Retransmissions of each packet, if any, may be sent on the resource block used for the first transmission of the packet. The UE may perform blind decoding to recover packets sent to the UE. In another aspect, semi-static group assignment may be used, and the UE may be assigned a group of resource blocks that may change periodically or based on trigger events.
Abstract:
Admission control is performed on a forward link shared packet data channel based on the measured delay per unit of data transmitted on the channel or the data throughput on the channel. In another embodiment, statistical analyses of channel quality metrics received at a base station are compared to the data rate used to serve mobile stations on the packet data channel to perform admission control. In any case, admission control may be performed for a new call setup request, hard handoff or virtual handoff. Admission control may be performed independently for a plurality of Quality of Service (QoS) flow categories, such as real time, best effort, rate sensitive, or QoS categories defined by cost. Users may be allocated among QoS flow categories as necessary to maintain performance.
Abstract:
A method and apparatus provide for setting the initial transmit power of secondary reverse link carriers used by mobile stations in conjunction with primary reverse link carriers. In one or more embodiments, a mobile station sets the initial transmit power of a secondary reverse link carrier relative to the transmit power of the primary reverse link carrier as a function of initialization transmit power information transmitted to the mobile station, which directly or indirectly considers reverse link loading information. Additional considerations may include differences in active sets associated with the primary and secondary reverse link carriers and/or sector switching activity of the mobile station.

Aspects of the present disclosure include methods, apparatuses, and computer readable media for generating a first scrambling identification (ID), generating a first scrambling sequence based on the first scrambling ID, scrambling a first set of information based on the first scrambling sequence to generate a first plurality of information bits, generating a plurality of repeated copies of the first plurality of information bits scrambled using the first scrambling sequence, and transmitting a first transmission burst including each of the plurality of repeated copies of the first plurality of information bits on different ones of a first plurality of resources in a communication channel.
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to use one or more channel state information (CSI) omission configurations for omitting portions of a CSI report. For example, a UE may receive a trigger to report CSI, and the UE may identify that a payload of the CSI report exceeds a capacity of resources for transmitting the report. As such, the UE may determine to use one or more CSI omission configurations, where each CSI omission configuration may correspond to dropping different portions of the CSI report. The selection of the CSI omission configuration to use may be based on a set of parameters associated with CSI reporting. In some cases, the UE selects the CSI omission configuration based on an explicit indication from the base station. Additionally or alternatively, the UE may implicitly determine the CSI omission configuration based on the parameters.
Abstract:
Aspects of the present disclosure relate to techniques for non-codebook based uplink (UL) transmission. In some cases, a user equipment (UE) may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.
Abstract:
Certain aspects of the present disclosure relate to communication systems, and more particularly, to a partial channel state information reference signal (CSI-RS) port indication. A method by a base station (BS) includes configuring a user equipment (UE) with a CSI-RS resource, of one or more CSI-RS resources associated with a CSI report. The CSI-RS includes a set of CSI-RS ports. The BS provides a first indication to the UE of a subset of groups of the CSI-RS ports to be used by the UE for channel measurements and/or a second indication to the UE of a subset of groups of the CSI-RS to be used by the UE for interference measurements. Based on the indication, the UE performs channel measurements and/or interference measurements using the indicated subset of CSI-RS ports.
Abstract:
Techniques and apparatus for configuring transmission rank and/or precoder(s) to support uplink non-codebook based transmission are provided. One technique includes receiving sounding reference signal (SRS) resource(s) from a user equipment (UE), where each SRS resource is associated with one or more precoded ports. At least one of a transmission rank or a set of precoders is determined based on the SRS resource(s). An indication of at least one of the SRS resource(s) is signaled to the UE. The UE uses the indication of the at least one of the SRS resource(s) to send an uplink transmission.
Abstract:
Certain aspects of the present disclosure provide techniques for indicating a purpose for a reference signal. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving an indication of a purpose of a reference signal (RS) from a base station (BS) and processing the RS in accordance with the indicated purpose.
Abstract:
In a method of wireless communication, a UE receives a configuration to receive a CIF for a serving cell of a plurality of serving cells. In addition, the UE monitors a PDCCH on a primary cell of the plurality of serving cells. Said primary cell is different than said serving cell. Furthermore, the UE assumes information received in the PDCCH is for said primary cell when the received information has a common payload size and is in a common search space with a first CCE index in the common search space being equal to a first CCE index in a UE specific search space.
